Pirolityczna chromatografia gazowa i jej nowe mozliwosci w analizie polimerow

摘要

Major conditions are formulated to make pyrolysis gas chroma-tography (PyGC) a method that yields reliable and repeatable results, espe-cially when nonvolatile organic substances (polymers) are analyzed. Equip-ment for PyGC is characterized and examples are given of studies on various types of polymers. Author’s own modification of PyGC is presented, involv-ing the use of a pyrolysis attachment with the mobile reaction zone. The re-sulting data are compared with those obtained by conventional PyGC (Fig.5). A two-step analysis by the modified method is described, applicable to materials containing volatile and nonvolatile species.
